The night’s preliminary, affiliate-based Nielsen results are shaky due to roughly 25 minutes of news coverage consisting of the Obama speech followed by the Republican response at 9 p.m. ET. The lineups for viewers in the western part of the country were not affected.

At ABC, the penultimate episode of this season’s ”The Bachelorette” averaged a 2.3 rating/7 share in adults 18-49 and 7.9 million viewers overall during the 8 o’clock hour, and then concluded following the news coverage with its second hour from 9:30 to 10:30 p.m. (roughly 2.4/6 in 18-49, 7.9 million viewers overall).

Fox was strong in Monday’s opening hour with ”Hell’s Kitchen” (2.5/8 in 18-49, 5.8 million viewers overall), which appears to have been the night’s No. 1 program in 18-49. Following the news coverage, a repeat of ”MasterChef” was joined in progress and earned a 1.4/4 in 18-49 and 3.4 million viewers overall during the 9:30 p.m. half hour.
